Metre bridge

In the circuit shown in figure. A metre bridge is shown in its balanced state. The metre bridge wire has a resistance of a 4 ohm/cm. calculate the value of the unknown resistance X and the current drawn from the battery of negligible resistance.

In the following circuit, a metre bridge is shown in its balanced state. The metre bridge wire has a resistance of 1 ohm/cm. calculate the value of the unknown resistance X and the current drawn from the battery of negligible internal resistance.

One ideal cell is used to drive current in a metre bridge circuit. In an experiment x is the balancing length obtained. If we replace the wire of the metre bridge with another wire of material having more rsistivity and lesser diameter, the new balancing length will be

What is end error in a metre bridge ? How is it overcome ? The resistances in the two arms of the metre bridge are R=5Omega and S respectively. When the resistance S is shnted with an equal resistance, the new balance length forund to be 1.5 i_(1) , Where I_(1) is the initial balancing length. Calculate the value of S.

In a metre bridge when the resistance in the left gap is 2Omega and an unknown resistance in the right gap, the balance point is obtained at 40 cm from the zero end. On shunting the unknown resistance with 2Omega find the shift of the balance point on the bridge wire.
